Automotive and motorcycle components
Automotive components must possess high strength, wear resistance, and safety and reliability. Typical applications include key components such as crankshafts, cylinder blocks, calipers, and wheel rims. These parts must withstand high-speed rotation, repeated impacts, and high-temperature friction during operation, therefore, lightweight design and manufacturing must simultaneously pursue structural rigidity.
Damping rod
Damping rods are key components used to absorb and dissipate vibrational energy, and are widely used in aerospace, automotive, locomotive, and precision machinery fields to reduce resonance and noise and improve system stability and lifespan. They consist of a metal shell and damping material, and must simultaneously provide structural support and vibration absorption under dynamic loads and long-term operation. During processing, the toughness of the materials and the composite structure make them prone to deformation or thermal effects; the damping layer must be uniformly filled and firmly bonded to the metal to avoid bubbles, delamination, or stress concentration.
Caliper
The braking system components of automobiles and motorcycles use hydraulic pistons to push brake pads to clamp the disc, generating friction to achieve deceleration and braking effects. The caliper contains a deep cavity structure, oil passages, and multiple sets of piston seats. The manufacturing process must precisely control coaxiality, sealing surface flatness, and hole position to ensure stable and reliable braking performance under high temperature, high load, and frequent braking conditions.
Rim
Wheel rims bear the weight of the tires and transmit driving and braking torques, directly affecting vehicle safety, handling stability, and energy efficiency. They are mostly made of lightweight materials such as aluminum alloys. Because one-piece wheel rims are thin-walled and geometrically complex rotating components, they are susceptible to deformation due to residual stress and processing heat during forming, deep hole machining, and subsequent finishing. Therefore, manufacturing must precisely control roundness, concentricity, hole position, dimensional tolerances, and surface quality, while avoiding stress concentration and fatigue crack formation.
